HARROW OR CULTIVATOR.

SPECIFICATION forming part of Letters `Patent No. 760,527, dated May 24, 1904.

Application filed October 3, 1903.

To all whom, it may concern; j

Be itlmown thatI, OLTVER C. Curremacitizen of the United States, residing at Palestine, in the county of Andersonand State of Texas, have invented a new and useful Harrow or Cultivator, of which the following is a speciiication.

This invention relates to that class of harrows and cultivators which are provided with spring-teeth and in which the spring-teeth, as well as the tooth-carrying members, may be set or adjusted to a great variety of positions, according to the work that is to be performed, the structure of the'device being the same whether it is used for harrowing or for cultivating purposes.

My invention has for its object to provide a device of the class referred to which shall possess superior advantages in point of simplicity, durability, and general efficiency and in which a great variety of different adjustments may be had without altering the construction of the component parts of the device, said parts or members being simply set or adjusted according to the work that is to be performed.

With these and other ends in view my invention consists in the improved construction and combination of parts, which will be hereinafter fully described,and particularly pointed out in the claim. l

In the accompanying drawings, Figure l is a plan view of the device, showing the toothcarrying members set in alinement with each other and in a straight line, dotted lines in this figure being used to indicate the position of the tooth-carrying members when the ends of the latter have been moved in a forwardvdirection. Fig. 2 is a plan view showing the tooth-carrying members adjusted in a rearwardly-diverging position, dotted lines in this iigure being employed to indicate the two members placed in alinement with each other, but at an angle to the tongue or traction mem- Fig. 3 is a longitudinal sectional view taken on the line 3 3 in Fig. 1. Fig. 4 is a detail view, on an enlarged scale, of one of the Fig. 5 is a sectional view taken on the line 5 5 in Fig. 2.

Corresponding parts in the several figures Serial No. 175,652. (No modeld are indicated by similar numerals of reference. j

In theconstruction of my improved harrow and culti vator I avail myself ofabeam l, which is provided at its rear end with handles 2 of ordinary construction. The tooth-carrying members of my improved device comprise two plates 3 3 of suitable dimensions, each of said plates being provided with a plurality of perforations 4 4, disposed equidistantly near one edge thereof. Each of said members is also provided with a plurality of segmental slots 5 5, disposed concentrical ly with the perforations 4 and adjacent to the opposite edge of the plate 3. In the accompanying drawings I have shown each of the tooth-carrying members or plates provided with four perforations 4 and with four slots 5; but it is obvious that the number of these perforations may be reduced or increased when desired.

The teeth of my improved harrow or cultivater, which are designated 6, are springteeth of ordinary construction, each tooth being extended across one of the carrying members or pl .tes 3 and provided with two perforations 7 and 8 for the attaching-bolts 9 and 10, one of which extends through one of the perforations 4 and the other through one of the segmental slots 5 in the side plate. It is obvious that by loosening the nuts upon the respective bolts the teeth 6 may be adjusted to any desired position with relation to the tooth-carrying plate within the limit of the length of the slots 5. It follows that said teeth may be adjusted either at right angles or obliquely with relation to the tooth-carrying plates. Hence when the latter are connected with the beam in the various positions indicated. in Figs. 1 and 2 the teeth may be readily adjusted directly in the plane of the line of draft.

In connecting the tooth-carrying plates or members 3 3 with the beam 1 the inner ends of said plates are permitted to overlap until the two innermost perforations 4 shall be in alinement with each other, when a bolt l1, extending vertically through the beam, may also be extended through said perforations 4 and when tightened serve to hold the tooth-carrying members in the desired position. An ad- IOO ditional bolt 12 extends through the beam l and through the inner overlapping slots 5, and itfollows that when the nuts are tightened upon said bolts the parts will be held very securely in any position to which they may be adjusted with relation to each other. In any case the central tooth will be adjusted upon the two bolts 11 and 12 and also consequently always be disposed in the line of draft, while when the position of the tooth-carrying mem bers is shifted the remaining teeth require to be properly adjusted, as will be readily understood.

In the operation of my invention I do not confine myself to the relative positions of the independent members herein described, and shown in the accompanying drawings, it being obvious that the component parts of the device may be disposed, arranged, and used in any relative position to which they may be adjusted. I also detach the tooth-carrying members and connect the same temporarily with other implements. It will be understood, therefore, that I do not limit myself to the precise structural details and modes of arrangement herein set forth, but reserve the right to any changes, alterations, and modications Within the scope of my invention which may be resorted to without departing from the spirit or saeriiieing the utility oi' the same.

Having thus described my invention, I Claim- An implement of the class described, comprising' a beam, a pair of tooth-carrying members, each provided with a plurality of perforations and a plurality of corresponding segmental slots concentric with said perforations, the inner endsvof said members being overlapped and connected with the beam by means of a pair of bolts engaging the perforations and slots at the inner overlapping ends of said members, a sorinotooth mounted upon the said connecting-bolts, additional sprinfreeth adjustably connected with the too 1-carrying members, the connecting means consisting of bolts engaging the perforations and slots in said mem bers and corresponding perforations in the teeth, and nuts upon said bolts.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
